HORSESHOE WITH REMOVABLE CALKS.

SPECIFICATION forming part of Letters Patent No. 484,740, dated October 18, 1892.

Application filed February 18, 1892. Serial No. 421,968. (No model.)

To all whom it may concern:

Be it known that I, CHARLEs B. HULBERT, of Ironia, in the county of Morris and State of New Jersey, have invented a new and Improved Horseshoe, of which the following is a full, clear, and exact description.

My invention relates to improvements in that class of horseshoes which have removable calks; and the object of my invention is to produce a cheap, strong, and durable shoe of this class in which means are provided for quickly changing the calks so as to provide the shoe with a calk of any desired style, to provide a perfectly-seen re means of fastening the calks, and also to provide a simple and secure method of holding the toe-piece of the shoe in place.

To this end my invention consists in a horseshoe the construction of which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a longitudinal section of the horseshoe embodying my invention, the section being taken centrally through the toecalk and through one of the heel-calks. Fig. 2 is an inverted plan of the shoe with a portion of the toe-calk and one of the heel-calks broken away. Fig. 3 is a broken front elevation, partly in section, showing in detail the toe-piece and the means of fastening the toe piece and toe-calk. Fig. at is a detail perspective view, partly in section, of the heel of the shoewith the calk removed. Fig. 5 is a detail view of a peculiar form of nail used to fasten the toe-calk, and Fig. 6 is a perspective view of a special tool used in fastening and unfastening the calks.

The shoe 10 is, in general, like an ordinary horseshoe and may be made in any desired style, it having the usual nail-holes 11 on opposite sides thereof, and the toe of the shoe is thickened on the under side, as shown at12, and in this thickened portion is a transverse dovetail groove 13, extending from one end of the thickened portion to nearly the opposite end,

the groove being open on the under side and having its upper wall slightly convex, as shown at 14. in Fig. 1, This groove or recess 13 is adapted to receive a tongue l5,shaped to fit the groove and formed on the upper side of the toe-calk 16, which calk may be of any desired shape, so long as it has a flat upper shoulder to rest against the thickened portion of the shoe, and the tongue 15 is prolonged at one end so as to extend a little beyond the calk, as shown at 17, and lie flat against the body portion of the shoe 10, as best shown in Figs. 2 and 3, this prolonged end of the tongue having at its outer end a notch 18 adapted to receive anail 19, which nail may be also driven through one of the nail-holes 11, and will thus bind the toecalk securely in place.

It will be seen that there will be no particular strain on the nail 10, it serving merely to prevent the calk from slipping out. The nail 19 has a perforated head 20, and when the calk is to be removed the special tool 21 (shown in Fig. 6) is used, this tool having one bent and pointed end 22 and having another bent-chisel end 23. When the nail 19 is to be removed, the point 22 of the tool is inserted in the perforation of the nail-head, and the nail may be pried out so as to be grasped by ordinary pinchei's. In the front of the shoe 10 is a dovetail vertical recess 24, which tapers upward and which is adapted to receive a common form of toe-piece 25, and the toe piece is prevented from dropping out of the groove by the toe-calk 16, the front upper portion of which extends beneath the toe-piece. If for any reason the toe-calk should not be wide enough to extend beneath the toe-piece, it may, while hot, be flattened slightly with the hammer, so as to extend beneath the toepiece and properly support the same.

The heels 26 of the shoe are thickened slightly, and each heel has in its front sidea rearwardly-extending recess or pocket 27, which is adapted to receive a rearwardly-extending lug 28 on the heel-calk 29. The heelcalk 29 may be of any approved style, and it has a shoulder 30 adapted to extend opposite the front portion of the heel 26, and the tongue 28 extends horizontally rearward from this shoulder, as best shown in Fig. 1.

The heel-calk 29 has a forwardly-extending tapering portion 31, which is flat on the upper side, so as to rest firmly against the body of the shoe 10, and near the front end of this prolongation is an upwardly-extendingrstud 32, adapted to enter a recess 33 in the under side of the shoe, and thus prevent the calk from slipping out of place. Each heelcalk 1s also provided near the front end of the prolongation 31 with a nail-hole 34, adapted to register with one of the nail-holes 11, and .when the shoe is applied to the foot of the horse a nail may be driven through the hole 4 and through the horses hoof, thus fastenmg the calk in place. Instead of usinga long nail, a short nail may be used, as shown by dotted lines in Fig. 1, and afterthe nail has been driven through the prolonged end 31 and through the body of the shoe it may be clinched on the upper side of the shoe by means of the tool 21,thechisel-point 23 being placed against the upper portion of the nail, and then by striking upon the tool with a hammer the nail may be clinched. At the extreme'front ends of the prolongations 31 are notches 35,.

which are made to come adjacent tothe holes 11 of the shoe, and when the nails are driven through the shoe they will engage the notches and serve as an extra precautip against the slipping of the heel-calks. Theis uds32 cause the heel-calks to hang to the shoe-body, and whenthe calks are removed the chisel point 23 may be driven between the prolonged ends 31 of the heel-calks and the body of'the shoe,

thus loosening the calks and enabling the tongue 28 to be withdrawn from the recess or pocket 27.

From the foregoing description itwill be seen that the calks may be made of any desired shape-that is, they may be either sharp or flat and they may be easily and securely fastened to the shoe while it is upon the horses foot or. as easily removed, and, as the calks usually wear out sooner than-the shoe, it will be seen that it maybe often necessary to shift the calks without shifting the shoe.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. As an improved article of manufacture,

a horseshoe having a recessedtoe and recessed heels and detachable calks having tongues to fit the recesses of the toe and heels and having prolonged ends with holes therein adapted to register with the nail-holes of the shoe, sub stantially as described.

2. The combination, with the shoe having a thickened toe with a dovetail groove or recess therein, of a toe-call: having a tongue adapted to slide into the recess and having a notch in the outer end of the tongue, which notch is adapted to register with a nail-hole of the shoe, substantially as described.

3. As an improved articleof manufacture, a horseshoe having a dovetail vertically-tapering recess in its too, a detachable toe-piece adapted to fit in the said recess, and a-removable toe-calk adapted to overlap the under side of the recess and toe-piece, substantially as described. 4

4. The combination, with the horseshoehaving thickened heels with forwardly-opening recesses therein, of the detachable heel-calks having rearwardly-extending tongues to enter the heel-recesses and having forwardly-e20 tending ends with studs thereon adapted to enter recesses in the body of'the shoe, said forwardly-extending ends having nail-holes therein to register with the sh'oe'nail-holes, substantially as described.

5. The combination, with the shoe having thickened heels-with forwardly-opening recesses therein'and recesses in its under side and in front of the heels, of the detachable .calks having rear-wardly-extending tongues to enter the heel-recesses and forwardly-exjtending portions adapted to fit against the bottom of the shoe, said forwardly-extending portions having studs thereon to enter the shoe-recesses, holes therein to register with the nail-holes of the shoe, and notched front ends arranged adjacent to the nail-holes of the shoe, substantially as described.
